For this case we have that by definition the growth of a population is a function of the form:
Where,
- <em>a: initial population </em>
- <em>b: growth rate </em>
- <em>x: number of years </em>
We observe then that the function is of the exponential type.
Answer:
C) Exponential
- Midpoint Formula:
Plug the coordinates into the midpoint formula and solve as such:
<u>Your midpoint is (5,-1).</u>
Answer: Option A
Step-by-step explanation:
In the graph we have a piecewise function composed of a parabola and a line.
The parabola has the vertex in the point (0, 2) and cuts the y-axis in y = 2.
The equation of this parabola is
Then we have an equation line
Note that the interval in which the parabola is defined is from -∞ to x = 1. Note that the parabola does not include the point x = 1 because it is marked with an empty circle " о ."
(this is )
Then the equation of the line goes from x = 1 to ∞ . In this case, the line includes x = 1 because the point at the end of the line is represented by a full circle .
(this is )
Then the function is:
